LS7 part numbers??
I'm itching to see part#s for the dry sump oil system. Even though the article linked below makes it appear it's a hybrid dry/wet sump and still uses the crank snout-mounted gerotor oil pump w/ a pickup in the pan, it may still be a worthwhile upgrade for road racing.

Thanks, I hadn't seen that. Dual gerotor pumps inside the timing cover explains GM's comfort w/ "dry sump" on a street car. Not likely they'd go traditional belt driven external accessory pump on a car they warranty. 
So many things to find. Not likely I'd have it ready for this upcoming track season, so at the earliest it's a next Winter project.

Have you seen the dry sump setups from ARE (Armstrong Race Engineering - not the guys from Canada). They have a cast pan that uses the factory pump as your pressure side and two scavenges via a traditional dry-sump pump on the side. Very nice setup and its actually pretty cheap in comparison to a traditional dry sump setup.
